SPECIFICATION forming part of Letters Patent No. 489,436, dated January3, 1898.

To a/ZZ whom it may concern.:

Be it known that we, LEoNADUs E. KARNES and lKENEss F. RICE, citizens ofthe United States, residing at Eureka Springs, in the county of Carrolland State of Arkansas, have invented a new and useful Tire-Heater, ofwhich the following is a specification.

This invention relates to tire heaters and the object of the same is toimprove the construction of devices of this character.

To this end the invention consists of the details of constructionhereinafter more fully described and claimed, and as illustrated in thedrawings, in which:

Figure 1 is a plan View of the device. Fig. 2 is a longitudinal sectionof the same on the line 2-3 showing the device as embedded in a forge.Fig. 3 is a similar section omitting the branch pipe and showing thedeviceas adapted to heat the tires by gas. Fig. 4 is an enlargedperspective detail of one of the spokes and its adjustable tip. Fig. 5is a similar detail showing the tip as constructed in the form of aburner.

Referring to the said drawings, the letterZ designates a forge of theordinary construction and lled with ashes or cinders as is usual.

A is a fan or other air-blast directing a blast of air through the pipeC which extends to a point beneath the center of the'forge and thenturns upwardly into the box or chamber F which is embedded in thecinders. From this box radiates a number of spokes S, which are of ironpipe communicating with the interior of the box and which have upwardlyturned outer ends E. In these ends are swiveled nozzles N whose freeends are bent at right angles to their bodies. These nozzles are eitherL-shaped and open at their free ends as shown, or are T-shaped withperforations in their heads causing them to serve as burners, as shownin Fig. 5, and in either case they form adjustable tips whose shanks areswiveled in the upturned ends E of the spokes S. Rising from the pipe Cis a branch pipe B which is bent forwardly and passes through the wallof the forge where it is adapted to v deliver a blast of air to the livecoals in the forge when the latter is to be used for the ordinarypurposes. This branch pipe has a tip or nozzle at its free end which mayextend to a point above the chamber F as in Fig. l, or only slightlyinto the forge as in Fig. 2.

b and c are valves in the branch pipe B and in the main pipe Crespectively, and these valves may be operated to direct the blast ofair either to the chamber F and thence to the adjustable tips, or to there in the forge as may be desired.

When gas is used the fan may or may not be dispensed with as desired,but the gas is fed through the pipes in the same manner as the airexcept it makes its exit through nozzles in the shape of burners as willbe understood.

It will be obvious that gasoline might be used, in which case thechamber F would constitute the vaporizing chamber and in this case aslight change in the construction and arrangement of parts would benecessarily made without departing from the spirit of our invention.

In using our machine the tire to be heated is placed upon the cindersover the adjustable tips, the latter being turned in the ends E so thattheir ends will direct a blast of air onto the coals at the properpoints, or if they be burners so that the burning fluid will be directedagainst the tire. The coals are then banked up around the tire and theblast of air, gas, gasoline, air' and gas, or air and gasoline isdirected through the pipe C, chamber F, spokes S, ends E, and tips N andcontinued until the tire is heated to the desired degree. When it isdesired to use the forge for the ordinary purposes, the valves b and care so operated as to direct the Huid through the branch pipe B to theforge and to the coals there located, a suitable nozzle being here usedif desired. By properly adjusting the valves b and c, part of the fluidmay be directed through each pipe, in which case the forge will beheated not only at the tip of the pipe B but in a ring around thechamberF varying in size according as the adjustable tips are turned andas the fluid is ejected from the nozzles thereof.

Although we have shown and described the branch pipe B, it will beunderstood that it can be omitted if desired as shown in Fig. 3

ICQ

and the tire heater arranged in a forge by itself especially adapted forthis work.

What is claimed, as new is:-

I. The combination with a forge, of an air pipe C, a fan arranged at theouter terminus of the pipe, a chamber F at the upper end thereof,radiating hollow spokes S communicating with and extending horizontallyfrom the sides of said chamber and having upturned ends E, andadjustable tips whose lower ends are swiveled in said upturned ends andWhose free ends are bent at an angle thereto and provided with nozzlesN, as and for the purpose set forth.

2. In a tire heater, the combination of the fan A, the horizontal pip,eC leading therefrom and turned upwardly at its opposite end, the chamberF at the upper end of said pipe, the hollow radiating spokes Scommunicating with and extending from the sides of said chamber, and thenozzles N at their outer ends; the forge for containing einderssurrounding said nozzles, and the branch pipe B, rising from saidhorizontal pipe C and extending into the forge, as and for the purposeset forth.

3. In a tire heater, the combination with the fan A, the horizontal pipeC leading therefrom and turned upwardly at its opposite end, and thering of nozzles N surrounding and connecting with said turned up end; ofthe branch pipe B rising from said horizontal pipe and extendingforwardly to a point within said ring,the valvesb and c in said pipes,and the forge Z foi-containing cinders su rrounding said ring, as andfor the purpose hereinbefore set forth.

In testimony that we olaiin the foregoing as our own we have heretoaixed our signatures in presence of two witnesses.
